Cosmological Origin of the Lowest Metallicity Halo Stars
Xavier Hernandez, Andrea Ferrara
We explore the predictions of the standard hierarchical clustering scenario of galaxy formation, regarding the numbers and metallicities of PopIII stars likely to be found within o…
Dust Formation in Primordial Type II Supernovae
Paolo Todini, Andrea Ferrara
We have investigated the formation of dust in the ejecta of Type II supernovae (SNe), mostly of primordial composition, to answer the question of where are the first solid particle…
Physical Processes at Cosmic Dawn
Andrea Ferrara
In this summary paper I will focus on the four main topics discussed at this Conference: (i) First luminous sources in the universe, (ii) Reionization, (iii) Intergalactic medium a…
Detecting the First Objects in the Mid-IR with NGST
Benedetta Ciardi, Andrea Ferrara
We calculate the expected Mid-IR molecular hydrogen line emission from the first objects in the universe. Due to their low masses, the stellar feedback from massive stars is able t…
Cosmological Reionization Around the First Stars: Monte Carlo Radiative Transfer
B. Ciardi, A. Ferrara, S. Marri +1
We study the evolution of ionization fronts around the first proto-galaxies by using high resolution numerical cosmological (Lambda+CDM model) simulations and Monte Carlo radiative…
Mixing Metals in the Early Universe
Andrea Ferrara, Max Pettini, Yuri Shchekinov
We investigate the evolution of the metallicity of the intergalactic medium (IGM) with particular emphasis on its spatial distribution. We propose that metal enrichment occurs as a…
